I am not familiar with the safety of travel by van from Mexico City Airport to the Spa resort at Ixtapan. I went there several years ago and remember a two hour ride through rural areas. Have there been any problems? The vans are clearly identifiable and would be known to carry tourists from the U.S. I would really like to return, but have qualms. Don't want to risk kidnap for ransom or robbery. I loved the spa resort. We went right after 9-11 and the staff really appreciated that our party didn't cancel! The spa treatments were great, and the water aerobics classes excellent.
